Neil Armstrong autograph set to lead stellar signature sale

The estimate given for a Neil Armstrong autograph confirms our index's findings

A Neil Armstrong autograph has been given one of the highest estimates in an autograph sale that will be held on February 23 in Pennsylvania.

As detailed in the letter, Armstrong refused to give his autograph on the philatelic items, a policy he would later expand to all signature requests. This has left a short supply and has led to high values at auction.

The typed letterdisplays a bold autograph, andis expected to see bids of up to $1,500. Its estimate confirms the PFC40 Autograph Index's finding that, following his death in 2012, the Moonwalker's signature haswitnessed a significant leap in value.

The auction also contains a line-up of autographs from presidents, historical figures and aviators, as well as a selection of signed books.
